1. A load sharing method, comprising:
receiving, by a first root node device, a message sent by a leaf node device, the message comprising a first identifier and configuration information, the first identifier indicating the leaf node device, the configuration information indicating a configuration mode requested by the leaf node device for load sharing from a root node device group to the leaf node device, and the root node device group comprising the first root node device; and
determining, by the first root node device, a configuration result of the load sharing from the first root node device to the leaf node device by at least performing a hash calculation based on the first identifier and the configuration information from the message sent by the leaf node, wherein the first root node device determines whether it is a primary root or a secondary root based on the configuration result.
